SPECIFICATION forming part of Letters Patent No. 351,236, dated October 19, 1886.

Application filed November-1G, 1585. Serial No. 182,016. (No model.)

To all whom it may concern,.-

Be it known that I, FRANK A. WELLs, a citizen of the United States, residing at Ghicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Vater-Closets, which is fully described in the following specilicaiion.

This invention relates to the ,so-called siphon-closets,77 which are so constructed that the bowl is evacuated by the siphonic action of the dischargepipe and refilled by the afterwash, the Siphon being broken77 bythe admission of air.

It relates particularly to those closets in which the air is exhausted from or rareiied in the longer limb of the siphonic dischargepipe by means of the current of lushing-\'vater, an air-pipe from the top or crest of the siphon being protruded into the flushing-pipe, so that the air is drawn from it by the passing current of water. A serious defect in these closets arises from the inadequacy of this means of effecting the exhaustion of the air from the siphon, and the sluggish movement of the contents of the bowl in the process of evacuation which results. Another serious defect is that the air thus drawn from the siphon is discharged with the dashing-water into the bowl and thence into the room, and this air, having been previously confined over the water in the trap, is invariably charged more or less highly with sewergas which has been first absorbed and then given off by thc water in the trap-that is, passed through the water in the trap from the sewer beyond.

This invention is designed to cure these defects and at the same time provide means for thoroughly flushing the trap and the soil-pipe.

It comprises, in addition to the usual waterpipe discharging into the bowl for the purpose of flushing the same, another water-pipe discharging into the closet-discharge or soilpipe beyond the siphon, and preferably, in order to accomplish a secondary purpose, into the trap between the siphon and the sewer and in the direction of the flow of water through the same, and an air-pipe from the crest of the siphon leading to and opening linto this latter water-pipe, so that the exhaustion of air from the siphon is effected by the water-current through this latter pipe, which will carry the foul air to a point such that it may escape through the Ventilating-ducts provided for the sewer and its connections,- rather than by the current of flushing-water through the iiushing-pipe, which would discharge the foul air into the bowl, and thence into the room.

It comprises, further, a preferred form of construction of the airpipe and water-pipes, whereby they are connected with the servicebox in a single fitting, which may be made complete and adapted to be inserted into the bottom of any plain wooden or other serviceboX.

It comprises, also, a device by which the amount of the after-wash may be regulated in putting in such tting, to correspond with the size of the bowl which it is designed to serve.

It comprises, also, a device for regulating the water-current, which operates to exhaust the siphon in such manner that the suction which said current causes may be increased or diminished, according to the cxigencies of the case, and that the proportion of the contents of the service-box which passes by the flushing-pipe and the said air-eXhausting pipe may be varied as desired or found necessary.

In the drawings, Figure l is a vertical section of a tank service-box and closet, including my invention. Fig. 2 is an enlarged vertical section of the fitting by which the several pipes are connected to the service-box, showing the nica-ns of regulating the afterwash and the air-exhausting current. Fig. 3 is a plan of said fitting.

A is the bowl.

B is the siphon.

C is the trap.

D is the soil-pipe.

E is the iushing-pipe leading from the bottom of the service-box M to the flushing-rim A ofthe bowl A.

E is the siphon-exhausting water-pipe having the funnelshaped mouth Ew protruded up through the bottom ot' the Servicebox M such a distance that below the upper edge of said mouth the box M shall be sufficient to contain the necessary amount ol' water for the afterwash. Said pipe E leads i'rom the servicebox to the aperture c2, by which it opens into the portion Cl oi' the trap C.

F is the air-pipe leading from the siphon B.

IOO

It penetrates the bottom of theservice-box M', passes up alongside of the pipe E', and is bent into the goose-neck F, which is protruded downward into the funnel El", and provided therein with the inverted funnel shaped mouthf.

N is the tank of usual construction and having the usual appurtenances for controlling the supply of'water thereto, and communicating with the service-box M by a large opening, n', closed by the valve N, which is operated in any convenient and well-known inanner, as by the pull-cord n, attached to the lever N2,1"rom which the chain or rod n2 extends to said valve.

For convenience of connecting the several pipes with the service-box, I provide the metal block P,which is preferably hollow, as shown, and has at the lower edge the flanges p p, provided with the screw or bolt holes p pf, by means of which said block may be secured into the bottom of the service-box, an opening being cut to admit it. The thickness of this block or shell P should be about the usual thickness of the plank or board which forms the bottom of the box, and it may be calked in, so as to make a water-tight junction with the boX. The flushingpipe E is inserted from below and soldered in at both upper and lower surfaces of the shell P. The pipe E is inserted from above. The opening which admits it through the upper plate of the shell P is plain, but that through the lower plate is screw-threaded, and said pipe has the lower end ofthe upper section-i. c., the section which is thus inserted from above-eX- teriorly screw-threaded, and being inserted through the plain opening in the vupper plate it is screwed down through the lower plate,

and may be firmly secured by the set-nut p2 on the lowerside. rIhe air-pipe F is inserted from above, and the pipe E having rst vbeen set at such position as will leave the proper depth for the water for the after-wash, the pipe F is brought down with its inverted funnel f inside the funnel El and made concentric therewith, preferably by bringing it first into complete contact with the interior sur-4 face of the latter, and then screwing the latter up a distance equal to the amount of vertical separation necessary to leave the desired annular aperture between said tunnels, and while in this position the pipe F is soldered into the block P, both at top and bottom surface of the latter. The pipe E may then be lowered until the desired annular aperture is obtained and the set-nut p'lsorewed up against the under surface of the block P. When the latter is hollow, as illustrated, a packingwasher, e', may be secured on its upper surface encircling the pipe E, to prevent the aecess of water to the .interior of the shell P. Any subsequent adjustment of the size of the aperture around the funnelf is made byloosening the set-nut p2 and screwing the pipe E u p or down, to diminish or increase said aperture. In order to prevent said adjustment breaking loose or straining the pipe E', Iprovde the-coupling En long 'enough and interiorly threaded far enough-to allow for all variation ever needed in said aperture. This coupling will be slipped ontothelower section of the pipe or the soldering-nipple E12, which terminates above in the flange E", before the lead section E, which makes the junction with the bowl, is wiped on.

When the water is admitted to the servicebox M, a part is passing out through the pipe E only while the service-box is iilling up to the level of the mouth'jof the funnel E10, making a fore-wash77 of the bowl. After the water passes said height, a part passes through E around the funnel f', and thereby draws air through pipe F from siphon B, producing a partial vacuum in the siphon and tends to induce its siphonic action, whereby the bowl is evacuated. The same water, passing on through the pipe E, is discharged through the aperture e2 into the section C2 of the trap C, and communicating motion to the water therein starts and drives it over into the soil-pipe D, thereby drawing the Water from the portion of the trap back of the aperture e2 and further increasing the siphonic action of the siphon B, and so hastening the movement of the contents of the bowl being discharged thereby. The air drawn from the siphon through the air-pipe F is' carried over` into the soil-pipe with the water from the. pipe E', and is thus prevented from gaining access to the bowl and thence to the room. Vhen the water in the service-box M has fallen below the level of the mouth of the pipe E, the water already in said pipe ilows out and the current through said pipe ceases, and in consequence the siphonic action of the siphon I3 ceases, air being admit ted to it through pipe F. The water remaining in the service-box below the level of the mouth of the pipe E continues to iiow out through the pipe E and enters the bowl, constituting an after-wash, which lls up the bowl to the level of the bridge of the siphon.

For convenience and compactness I prefer to make the lower portion of the pipe E integral with the closet, being a duet, E, in the metal or crockery-ware of which the closet and its siphon and traps are made, and it is so shown in the drawings 5 and in that case said duct terminates in a suitable nipple, to which the remainder of the pipe can -be conveniently connected.

I do not iind it essential that the water ilowing through the pipe E should discharge into the trap; but it may, though not with so perfect results as a means of producing suction through the siphon, be made to discharge into the soil-pipe entirely beyond the siphon, as shown in the dotted lines e in Fig. l.

I claiml 1. In combination with the bowl, the sivphonie evacuating-pipe and the trap between said pipe and the soil-pipe, the water-pipeE, discharging into the trap in the direction of the flow through the same toward the soil-pipe,
